This has definitely been fixed. I use the 18f452 all of the time now and
know that this okay. As an interim fix, you may wish to try changing the
goto's to bra's. Also, instead of diving into the gtk extra 2.0 hell pit,
you may wish to update your code from CVS and configuring it to run with
the older gtk stuff. That's still working AFAIK. (All you need to do is
run configure like this: ./configure --enable-gtk1 )
